“…Herein, subcritical water was used as a unique alternative and environmentally friendly method that offers many advantages. 23 In the literature, there are several investigations about the solubilities of pharmaceuticals in single and binary solvent mixtures, which is important for pharmaceutical industry. Approximation model equations are useful to predict the solubilities of the pharmaceuticals over a wide range of temperatures.…”

In this study, solubility and degradation of paracetamol were examined using subcritical water. The effect of temperature and static time was investigated during the solubility process in subcritical water at constant pressure (50 bar). The experimental results showed that temperature and static time have crucial effects on the degradation and solubility degrees. The maximal solubility of paracetamol was obtained at 403 K as (14.68±0.74)×10 3. An approximation model for the solubility of paracetamol was proposed. O 2 and H 2 O 2 were used for the degradation of paracetamol. The maximum degradation degree was found as 68.66±1.05 % and 100±0.00 % using O 2 and H 2 O 2 , respectively.

“…RSM is an advantageous statistical technique which has been widely used to assess the optimum experimental variables and evaluate the performance of a system. 37,45 The main goal is to optimise the response in RSM over other independent variables as well as to predict responses using theoretical equations, by carrying out a limited number of experiments. Since Box and Wilson first introduced the CCD, the use of the CCD has increased even more due to being the most efficient method among many types of RSM designs.…”

“…38 Therefore, many researchers have been widely used an optimization method called response surface method (RSM) to overcome these problems. [37][38][39][40][41][42][43][44][45] RSM is a chemometric technique using one of the several types of statistical design methods. 31,38 This technique provides an evaluation of the interaction between independent variables and the response, besides providing the optimization of variables at any time.…”

An environmentally friendly method to decontaminate the olive mill wastewater, which is encountered as a major environmental problem is presented in this study. The removal of both polyphenolic and aromatic content and the degradation of wastewater of olive mill supplied from Mersin/Turkey region were investigated by the subcritical water oxidation method using H 2 O 2. The central composite design of response surface methodology was used to assess the effects of temperature, treatment time, and the concentration of oxidising agent. The reliability of the employed method was proved by ANOVA. The optimum experimental parameters were determined and theoretical equations were proposed in each case. The highest chemical oxygen demand removal, dephenolisation and dearomatisation values were obtained as 85.74, 96.13 and 95.94 %, respectively.

“…In recent years, due to the growing interest in subcritical fluid technology, a number of novel approaches have been proposed to measure the solubility of organic components in pressurized hot water [10][11][12][13][14][15][16][17][18][19][20]. These methods can be basically classified into static and dynamic methods [21].…”

In this experimental investigation, the solubility of β-carotene in pressurized hot water was measured at temperatures in the range of (70-130) °C and the pressure of 20 bar by using a dynamic method. The influence of different variables, including temperature and flow rate in the range of (0.15-0.64) ml/min, on the solubility of β-carotene was investigated. Furthermore, the optimization of these parameters was done through the experimental design by using factorial methodology. The results of the experiments showed that the temperature was the main parameter affecting the solubility of β-carotene in pressurized hot water. The best conditions for solubility of β-carotene in pressurized hot water were the temperature of 85 °C and a flow rate of 0.64 ml/min. β-carotene’s solubility data in pressurized hot water were correlated with the dielectric constant values of the solvent mixture.
